We continue to use this simple and essential stain today, which has remained unchanged for well over a century.

The hematoxylin stains cell nuclei blue, and eosin stains the extracellular matrix and cytoplasm pink, with other structures taking on different shades, hues, and combinations of these colors. This stain combination was first introduced in by A. After tissues have been collected often as biopsies and fixed, they are typically dehydrated and embedded in melted paraffin wax , the resulting block is mounted on a microtome and cut into thin slices.

The stain has been unchanged for many years because it works well with a variety of fixatives and displays a broad range of cytoplasmic, nuclear, and extracellular matrix features. Hematoxylin has a deep blue-purple color and stains nucleic acids by a complex, incompletely understood reaction. Eosin is pink and stains proteins nonspecifically. In a typical tissue, nuclei are stained blue, whereas the cytoplasm and extracellular matrix have varying degrees of pink staining. Well-fixed cells show considerable intranuclear detail. Nuclei show varying cell-type- and cancer-type-specific patterns of condensation of heterochromatin hematoxylin staining that are diagnostically very important. Nucleoli stain with eosin.

Left, Computational staining and destaining of whole slide prostate core biopsy images with conditional generative adversarial neural networks CGAN. Row A, Deparaffinized native nonstained image patches entered into the neural network. Arrows in C-I indicate the 2 benign glands, all other glands represent tumors. Variation in labeling detail by annotators arrows are shown in D-III. Green indicates true positive; blue, false negative; and red, false positive. Activation maps of kernels of trained generator neural network model layers after feeding a native nonstained prostate core biopsy image patch without tumor as it gets computationally hematoxylin and eosin—stained. Rows show top 5 activation maps from layers L1 to L5 and L16 to L19 arranged in decreasing order of their activations from left to right columns I-V.

The oxidation product of haematoxylin is haematin, and is the active ingredient in the staining solution. Haematoxylin is not classified as a dye since the molecule possesses no chromophore. The in situ oxidation of haematoxylin is effected by the addition of a strong oxidant to the stain, in this case sodium iodate. Haematin exhibits indicator-like properties, being blue and less soluble in aqueous alkaline conditions, and red and more soluble in alcoholic acidic conditions. In acidic conditions, haematin binds to lysine residues of nuclear histones by linkage via a metallic ion mordant, in this case aluminium.

Hematoxylin and Eosin Staining of Tissue and Cell Sections

При этом дерево иногда приходится потрясти, чтобы собрать подгнившие плоды. И я уверена, что большинство наших граждан готовы поступиться некоторыми правами, но знать, что негодяи не разгуливают на свободе. Хейл промолчал.

 - Танкадо мертв. Все замерли в изумлении. Возможные последствия полученного известия словно пулей пронзили Джаббу. Казалось, тучный шеф отдела обеспечения системной безопасности вот-вот рухнет на пол.

Беккер глубоко вздохнул и перестал жаловаться на судьбу. Ему хотелось домой. Он посмотрел на дверь с номером 301. Там, за ней, его обратный билет.

Казалось, на директора его слова не произвели впечатления. - Должен быть другой выход. - Да, - в сердцах бросил Джабба.  - Шифр-убийца. Но единственный человек, которому известен ключ, мертв.

 Вас это смущает? - раздался у него за спиной звонкий голос. Беккер обернулся и тотчас почувствовал, что краснеет. Он уставился на карточку с личными данными, приколотыми к блузке стоявшей перед ним женщины. Глава Отделения криптографии АНБ была не просто женщиной, а очень привлекательной женщиной. - Да нет, - замялся .

 - Хейл выдержал паузу.  - Выпустите меня, и я слова не скажу про Цифровую крепость.

    Real-time on-site histopathology review of biopsy tissues at the point-of-procedure has great potential for significant clinical value and improved patient care.
